Abstract
A display device has a display area and a peripheral area, and includes an array substrate. The array substrate includes M number of pixel unit columns disposed in the display area and a first dummy electrode disposed in the peripheral area, where M is a positive integer greater than or equal to 2. The M number of pixel unit columns include a first pixel unit column to an Mth pixel unit column arranged in sequence. Each of the M number of pixel unit columns includes a plurality of pixel units arranged in sequence. The first dummy electrode is located on one side of the first pixel unit column. During a frame period, the first pixel unit column receives the first pixel signal, and the first dummy electrode receives the first dummy signal. The polarity of the first pixel signal is different from that of the first dummy signal.
